All of my specimens are from the lake area where I have found it infrequently in marshes, tamarack bogs, and ditches. I have a specimen from Lagrange County with this note: "This plant had 10-12 petals to a flower and nearby plants also had more than 5 petals to a flower. Only one plant with the normal 5 petals." Sometimes the inner row of petals is much reduced in size. This species has been reported 4 times from Clark and Jefferson Counties, the authors saying: "In meadows." Doubtless these authors meant hayfields because meadows, in the botanical sense, do not occur there. I do not believe this species occurs there but what these authors had at hand I can not determine. The manuals used by them to distinguish the species are definite as far as this species is concerned. More intensive collecting in southern Indiana may reveal the plant in a different habitat.

Geum aleppicum has flowers with jointed styles, with the upper part less than half the length of the lower segment. It is found in moist wooded areas at middle elevation. It looks very similar to Geum macrophyllum var. perincisum. There are some differences in leaf shape, but the best field character is the presence of hairs obvious with a hand lens on the distal style segment on Geum aleppicum and missing on the style of Geum macrophyllum var. perincisum.
